Key Knowledge:
• cell structure: prokaryotic and eukaryotic cells at light and electron microscope levels; cellular organisation;
• cell functioning: specialised parts of cells and their functions; biochemical processes including photosynthesis and cellular respiration in terms of inputs and outputs; general role of enzymes in biochemical activities of cells;
• internal and external environments of cells; plasma membranes; membrane transport including diffusion, osmosis, active transport; surface area to volume ratio;
• cell replication: purposes of cell replication (mitosis and cytokinesis); cell growth, cell size and cell division.

Suggested schedule for teaching this area of study
Big idea 1: All organisms are made of cells
Big idea 2: The plasma membrane and its component molecules make selective permeability possible
Big idea 3: Every cell is derived from a pre-existing cell.
Big idea 4: The cell can perform all activitues required for life
